Darvish will have his right arm in a sling for seven to 10 days, and he will then have a brace on the elbow. He will begin his rehab in the next few days and return to the Rangers' complex in Surprise. Darvish is expected to do his rehab work in Arlington during the regular season.
Darvish left his first Cactus League start on March 5 vs. Kansas City after one inning with tightness in his right triceps. An MRI and examination the following day indicated Darvish had a sprain of the ulnar collateral ligament in his right elbow. Dr. Keith Meister recommended surgery, an opinion that was shared by New York Mets medical director Dr. David Altchek, and by Andrews.
